Mounting structure of a small-sized acoustic component

Abstract

In a mounting structure of an acoustic component for mounting the acoustic component to a casing of an electronic equipment, the acoustic component is fitted in a cylindrical hole of a spacer that is formed of a resilient material. The spacer is fitted in a cylindrical hole of a mounting part which fits in or forms part of a casing of the electronic equipment. The spacer and the mounting part have a sound path aperture for allowing the passage of sound into and out of the casing. The mounting part is provided with a sound path groove along its outer surface for communicating with the sound path aperture of the mounting part. Because of the sound path groove, an accidental placement of an obstacle, such as a finger, cannot block the passage of the sound into or out of the sound path aperture.

       7. A mounting structure according to claim 1, wherein the diameter of said first sound path aperture of said mounting means is formed for preventing said sound path aperture from being blocked by impediments having a predetermined diameter. 
     
     
       8. A mounting structure according to claim 7, wherein the diameter of said first sound path aperture of said mounting means is between a range 1 mm and 5 mm. 
     
     
       9. A mounting structure according to claim 1, wherein the length of said sound path groove is formed for preventing the entirety of said first sound path aperture and said sound path groove from being blocked by impediments having a predetermined length. 
     
     
       10. A mounting structure according to claim 9, wherein the sum of the diameter of said first sound path aperture of said mounting means and the length of said sound path groove is larger than said predetermined length. 
     
     
       11. A mounting structure according to claim 10, wherein the sum of the diameter of said first sound path aperture of said mounting means and the length of said sound path groove is larger than 10 mm. 
     
     
       12. A mounting structure according to claim 1, wherein said mounting means is provided on a bottom surface of the casing of said electronic device. 
     
     
       13. An electronic equipment according to claim 1, wherein said mounting means is provided on a bottom surface of the casing of said electronic device. 
     
     
       14. An electronic device having a mounting structure for mounting an acoustic apparatus in a casing of the electronic device, comprising: mounting means formed integrally with the casing of the electronic device, said mounting means having a first cylindrical opening and a mounting plate, said mounting plate having a first sound path aperture formed in substantially the center of said mounting plate and a sound path groove extending from said sound path aperture along a portion of a bottom surface of said mounting plate;   a net member positioned on a top surface of said mounting plate of said mounting means, said net member having water repellent properties; and   spacer means formed of a resilient material and inserted into said first cylindrical opening of said mounting means, said spacer means having a second cylindrical opening and a spacer plate, said spacer plate having a second sound path aperture formed in substantially the center of said spacer plate and positioned adjacent to said first sound path aperture, said second cylindrical opening being formed for receiving the acoustic apparatus so that said spacer means seals the periphery of the acoustic apparatus.   
     
     
       15. An electronic equipment according to claim 14, wherein said first sound path aperture of said mounting means and said second sound path aperture of said spacer means are in alignment. 
     
     
       16. An electronic equipment according to claim 14, wherein the dimensions of said sound path groove are formed for preventing said sound path groove from being blocked by impediments having predetermined dimensions.
